CYTOSCAPE 2.8 MANUAL PDF

Cytoscape 3. To accomplish this goal, a technique involving level of detail LOD is being used. Based on the number of objects nodes and edges being rendered, an appropriate level of detail is chosen. For example, by default, node labels if present are only rendered when less than nodes are visible because drawing text is a relatively expensive operation. This can create some unusual behavior.

Raw Blame History. If you're familiar with former versions of Cytoscape, this version will feel completely familiar and you'll be all set to go. In future releases, we will continue to tweak and improve both the software and the documentation. This manual will be updated to reflect all the latest changes. While this is good news, networks created on v3. Consequently, Cytoscape v3. With v3. While Cytoscape runs with 32 bit Java versions, using a 64 bit Java allows the largest networks to be loaded and enables the fastest network processing.

For Windows, the default JRE download provided at java. While Cytoscape will run with a 32 bit JRE, it will be limited to loading only small networks. We recommend downloading and installing a 64 bit JRE. For Cytoscape to work properly, all files should be left in the directory in which they were unpacked.

The core Cytoscape application assumes this directory structure when looking for the various libraries needed to run the application. This latter step will cause you to lose all of the apps that you have installed via the App Store, so only do that if you are having problems or if you don't mind reinstalling your apps. The core apps will not be affected by this step.

An incorrect estimate may result in Cytoscape hanging at startup or Cytoscape unable to load your network. If Cytoscape misjudges the memory size or can't allocate enough memory, it could be that you're running with a 32 bit JRE and could get better results by installing a 64 bit JRE -- see the Install Java section above. While most users won't need to use this option, it can be useful for users who have multiple large networks loaded.

The file contains one option per line, with each line terminated by a linefeed, and an extra linefeed at the end of the file. Note that for the MacOS platform, the situation is slightly different -- if you are launching Cytoscape by clicking on the Cytoscape icon, you must edit the To access this in Finder, you will need to right-click the Cytoscape app icon and select "Show Package Contents", which will display the Contents subdirectory that contains vmoptions.

Some of the functions in Cytoscape use larger stack space a temporary memory for some operations, such as layout. The value should be specified in bytes. For example you can specify a network as a file assuming that myNet. Since only one session file can be loaded at a given time, this option may only specified once on a given command line. It is customary, although not necessary, for session file names to contain the.

You can specify as many networks as desired on a single command line. Properties can be specified either as a properties file in Java's standard properties format , or as individual properties. The property option subsumes previous options -noCanonicalization, -species, and -bioDataServer.

These functions are also available via the menus. Hover the mouse pointer over an icon and wait momentarily for a description to appear as a tooltip. This contains an optional network overview pane shown at the bottom left. This is useful when you want assign the network panel as much screen space as possible.

A popup will be displayed when you put the mouse pointer on a cell. If you click this control, the window will dock onto the main window. Then select the target node, a new edge will be added between the two nodes. In a similar way annotation objects can be added; pictures, shapes or textboxes; much like in MS PowerPoint or similar software.

Print Current Network It also provides the control of other view-related functionality. The bottom section of the menu lists a variety of layout algorithms which automatically lay a network out. Depending on which apps are loaded, the apps that you see may be different than what appear here. The below picture shows a Cytoscape installation without installed apps. The list will be different depending on the set of apps you have installed.

A network stores all the nodes and edges that are loaded by the user and a view displays them. Clicking on a network here will make that view active in the main window, if the view exists. Each network has a name and size number of nodes and edges , which are shown in the network manager. If a network is loaded from a file, the network name is the name of the file.

For this reason, a network in Cytoscape may not contain a "view". Networks that have a view are in normal black font and networks that don't have a view are highlighted in red.

You can also destroy previously loaded networks this way. You can maximize, minimize, and destroy network views by using the normal window controls for your operating system. It can be used to navigate around a large network view. The blue rectangle indicates the portion of the network currently displayed in the network view window, and it can be dragged with the mouse to view other portions of the network.

Zooming in will cause the rectangle to appear smaller and vice versa. The network file can either be located directly on the local computer, or found on a remote computer in which case it will be referenced with a URL. Choose the correct file in the file chooser dialog and press Open.

Some sample network files of different types have been included in the sampleData folder in Cytoscape. Here, you can choose either to create a new network collection for the new network, or load the new network into an existing network collection. When you choose the latter, make sure to choose the right mapping column to map the new network to the existing network collection.

Also, you can drag and drop links from a web browser to the URL text box. To work around this problem, Cytoscape supports the use of proxy servers. Proxy Settings An interactive GUI allows users to specify parsing options for specified files. The screen provides a preview that shows how the file will be parsed given the current configuration. As the configuration changes, the preview updates automatically.

In addition to specifying how the file will be parsed, the user must also choose the columns that represent the source and target nodes as well as an optional edge interaction type. For Excel Workbooks with multiple sheets, one sheet can be selected for import at a time. If the file has only one column, the created network will not contain any edges. The interaction type is optional in this format. This means that a network file is considered a combination of network data and edge column data.

A table may contain columns that aren't meant to be edge data. In this case, you can choose not to import those columns by clicking on the column header in the preview window. Other columns can be imported as edge data. Network table files can have edge table columns in addition to network data. If you select only a source column, it creates a network without interactions. This feature is useful with the node expansion function available from some web service clients.

By default, Tab and Space are selected as delimiters. For example, if you want to skip the first 3 rows in the file, set 4 for this option. This option can be used to skip comment lines in text files. This can be overridden by selecting the appropriate data type from the radio buttons provided.

For lists, a global delimiter must be specified i. Public Databases This selection will be saved as your default database list. Extend Network by public interaction database For example, in the screenshot, we have loaded the BRCA1 network from IntAct, and have chosen to merge this node's neighbors into the existing network.

If you want to search interactions by keywords or specific functions, this is the powerful query language to filter the result. The last option is for importing all interactions for the species i. Next, click on the target node. The Images below show the two steps for drawing an edge between two nodes. You can abort the drawing of the edge by pressing Esc key. Delete Selected Nodes and Edges You will be prompted to select a name for the group node.

Figure 1. In this screenshot, the expression data in the sampleData file galFiltered. The groups created by clustering are shown on the network. UCSF clusterMaker is a Cytoscape plugin that unifies different clustering techniques and displays into a single interface. Hierarchical, k-medoid, AutoSOME, and k-means clusters may be displayed as hierarchical groups of nodes or as heat maps. All of the network partitioning cluster algorithms create collapsible "meta nodes" to allow interactive exploration of the putative family associations within the Cytoscape network, and results may also be shown as a separate network containing only the intra-cluster edges, or with inter-cluster edges added back.

One of Cytoscape's strengths in network visualization is the ability to allow users to encode any table data name, type, degree, weight, expression data, etc. A set of these encoded or mapped table data sets is called a Style and can be created or edited in the Style panel of the Control Panel. In this interface, the appearance of your network is easily customized. For example, you can:.
